Hey! Wasn't _Incisivosaurus gauthieri_ synonymized with
_Protarchaeopteryx_? Must not be official yet.

It is official -- that means _published_. Whether you accept this or not is
solely at your very own discretion. "Taxonomic freedom". This is where the
term "subjective junior synonym" comes from. If you say "naaah, they're a
bit too different for my taste to be in the same genus", nobody can stop
you.
